I have one. I think it's the 7.3 from 2006. I bought it when I first started to ride again as an adult. I used it for about a month before I decided I should have gotten a road bike instead. I ended up buying a Bianchi road bike and haven't ridden the FX since. I loaned it to a friend of mine and she's now riding it.
If you really want an upright position, then it's a fine choice. What kind of riding do you want to do and what kind of distances? Is there a reason(s) you want to be in a more upright position?
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
